COMBINED LQCKAND LATCH.

SPECIFICATION forming part of Letters Patent No. 655,199, dated August '7, 1900.

V l Application file d, {1' anuaryli, 1900. Serial No. 249. (No'modelJ Be it known that I, Mosns E. CoLLINs,a citizen of the United States, residing at Brighton, in the county of La Grange and State of Indiana, have invented a new and useful Combined Lock and Latch, of which the following is a specification.

This invention relates to combined locks and latches, and has for its object to provide an improved device of this character in which all springs are dispensed wi th, the parts thereof are reduced to a minimum, and the latch is automatically operated by gravity, so as to be shot outwardly when the door-knob is released. It is furthermore designed to provide an improved locking-bolt which is securely held at its opposite limits and at the same time may be readily released and moved longitudinally by a single operation of a key.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will' be hereinafter more fully described, shown in the accompanying drawings, andjparticularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and'minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is an elevation of a combined lock and latch constructed in accordance with the present invention, one of the face-plates of the casingbeing removed so as to disclose the operating parts thereof and in their locked positions. Fig. 2 is a fsimilar View showing the lock and latch entirely withdrawn from the casing. Fig. 3 is a plan sectional view taken immediately above the locking-bolt.- Fig. 4 is a detail perspective Fig. 5 is a detail 6 is a detail sectional viewon the line 6 6 of Fig. 1.

Corresponding parts in the several figures is a substantially shaped latch, which is disposed so that its upper and lower arms are alined vertically and extend insubstantiallyhorizontal directions. The latchis pivotally mounted. upon' a suitable pivot-pin 3, which is carried by one of the face-plates of the easing and extends through the upper arm of the latch at a point nearer the outer end of the arm than the inner end thereof, whereby the The outer free extremity and normally projects outwardly through a slot or opening 5, formed in the adjacent edge of the casing. This gravity-latch is designed to be operated by means of the rod orobolt latch normally hangs in a slightly upwardly inclined position. act the lower arm of the latch forms the latch proper for engagement with a suitable keeper 8 provides an operative connection between the trip-lever and the gravity-latch, one end of said'li'nk being pivotally connected to the outer free end ofthe upper or pivotallymounted latch member, as indicated at 9, and

the oppositelower end of said link having a pivotal connection with the outer free end of the trip-lever 6. The hub of the trip-lever is provided with an angular opening 11 for the reception of the similarly-shaped door-knob bolt, so that when turning the latter to the right the horizontally-disposed trip-lever 6 will be drawn downwardly and through the link connection 8 will also move the outer free end of the pivotally-mounted latch member downwardly, thereby swinging the entire latch member upon the pivot-pin 3 and withdrawing the latch 4 into the casing, as indieated in Fig. 2 of the drawings. Immediately upon the release of the door-knobthe gravitylatch 2 will automatically resume its former position,with the latch 4 projecting outwardly beyond the casing, so as to be in position for engagement with a keeper. As indicated in Fig. 5 of the drawings, it willbe seen that one side of the'latcl1'4is beveled, as indicated thereof engages against said hub in the'normal position of the latch, whereby the*hub forms a stop to limit the outward movement of the latch. Moreover, the inner end of the U-shaped latch member engages against the; adjacent edge of the casing in the released position of the latch, so that the edge of the casing forms a stop to limit the inward move ment of the latch, and thus stops are coir veniently provided for limiting the movement 1 ottlie latch in opposite directions.

Located immediately below the gravitylatch" and in the same vertical plane with the latter is a l'ongitudinally-slidable locking-1 lb olt 1 3,th'e 'onterend of which is designed to project "outwardly through a slot or opening 14, formed inth'e adjacent edge of the casing.

As'sh'own in Fig. 4 of the drawings, the upper edge of the bolt is provided with a pair of notches oi-recesses and 16, and projecting lateral-1y outward from'the bottom of the outer notch l'b'is a stop shoulderor lug 17. The rear "end-of the bolt is elevated somewhat above the forward end thereof, so'as to form a tailpiece 1 8, and in the underside of the latter there is provided a substantially-semicircular open- .ing1'9,'andin the npper wall of the latterthere is provided "an angular notch or recess 20,5, which is located'substantially midway be-j;

tween the opposite sides of the semicircular; Topening and extends transversely of the bolt F 'Iliisleckingeboltis slida'bly supported upon :biock 21,'located within the casing, or it may; be's'np-ported upon the lower end of thecasing, as desired. Located in rear of this lockingbelt is ablock or shoulder 22, which limits; the inward movement of the bolt, and piv-g otally'eonnected to one side of the shoulder; is agravity-de'tent 23, which is located longi i'tndinallyat one side of the locking-bolt an'dg is'previded at its free end with a transverse; lug-or shoulder 24-, forming a c'atch for en-i gargenient with either of the sockets or re-; cesses 1'5 and 16 in the locking-bolt. Located immediately above the tailpiece 18 is a trans-' verse pin 25, carried by one side/of the cas- 'ingan'didesigned to gnide the locking-bolt in its longitudinal movement and to ward displacement of the bolt.

kelyis'then turned axially, so as-to engage;

I il; *"p'er'ate the locking-bolt, a suitable key is introduced through the keyhole-slot 26, formed in either side'of the casing, and the prevent upessence gages said detent and elevates the latter out of engagement with either of the notches 15 and 16 prior to the engagement of the key with the bolt, so that the latter is free to be moved when the key has been engaged with the notch 20. Moreover, the walls of the latter flare outwardly and downwardly, so that the key may not bind within the notch. It will now -be apparent that the guide and stoppin 25 is designed to prevent the rear end of *the bolt from being displaced upwardly by the engagement of the key with the notch 20, and also that the stop-shoulder 17 engages against the adjacent edge of the casing, so as-to limit the outward movement of the bolt. By reference toFig. 6 of th'e drawings it will be seen thatthelatch projects 'beyond 5 one side of the locking-bolt and-in the path of the upward movement of thedetent '23, so as to engage the latter and form a, stop jtolimi't the upward movement thereof, and thereby prevents accidental displacement of 'the' detent.

As indicated by'thedottd line in-FigQl of the drawings, the free end of thepivoted por- -tion of the gravity-latchis aiso'bevel'ed upon the same side as the opposite end of the latch, 'andthe latter is provided witha perforation 27-, and the latch is designed to be removed from the pivot-pin 8 a'nd inverted, so" that the perforation '27 mayreceive the pivot-pin, whereby the position of the arms are reversed, so as to arrange the beveled portion of the latch at either side of the'device, and thus accommodate the latch ro-doors moving in opposite directions. j What is claimed is j f V 1. In alatch, the combination withaeasi ng, of a substantially U-shaped la tch'h'aving-fene located between the sides or arm's'jof the latch, a linkcohnectioh betwe'enthe lever and the free end of'the pivoted side or member of the latch and eperatin'gjineans for' the latter.
